Can amniotic fluid protect developing fetal lungs against the harmful effects of oxidative stress?

BACKGROUND: Preterm births cause fetuses to be born without completing the development of their organs. Due to this undesirable situation, it is the pulmonary tissue which has to be most exposed to harmful effects of extrauterine environment. Early disappearance of the prophylactic and constructive effects of amniotic fluid (AF) on developing tissues, such as pulmonary tissue, facilitates the formation of pulmonary morbidities resulting from oxygen. Setting out from this knowledge, we wanted, in addition to assessing the beneficent effects of AF on pulmonary tissue, to study the importance of AF in morbidities of this tissue thought to originate from oxygen. METHODS: In this experimental study, while the study group was made up of the fetuses of pregnant rats exposed to hyperbaric oxygen, (hyperoxic pregnant rat fetuses-HPRF), the control group was formed of the fetuses of the rats pregnant in the usual room setting (normoxic pregnant rat fetuses-NPRF). The pulmonary and hepatic tissues taken from the fetuses of these pregnant rats on the 21st day of their pregnancy were compared biochemically and histologically. For biochemical assessment, total glutathione (tGSH), catalase (CAT), malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α) values and for histopathological assessment, apoptosis, alveolar wall count (AWC), vena centralis count (VCC) were included. RESULTS: Statistical significance was found in the pulmonary tissue values of tGSH on behalf of NPRF, and MDA on behalf of HPRF (p < 0.05). In liver tissue, statistical significance was detected in tGSH and CAT values in favor of NPRF and in MDA, and TNF-α values in favor of HPRF (p < 0.05). DISCUSSION: : Our study has demonstrated that AF protects the pulmonary tissue from the harmful effects of oxygen in the intrauterine period. In addition, our data have suggested that the pulmonary tissue's being deprived of the useful effects of AF owing to premature birth may be an important trigger in the occurrence of the pulmonary morbidities thought to result from oxygen.

Comparison of anesthesia management in transcatheter aortic valve implantation: a retrospective cohort study

Abstract Background and objectives We aimed to investigate the effects of two different anesthetic techniques in our patients who underwent transcatheter aortic valve implantation (TAVI). Methods In this study, 303 patients who underwent TAVI procedure with a diagnosis of severe aortic stenosis between January 1, 2012 and December 31, 2018 were retrospectively evaluated. The patients were divided according to the type of anesthesia given during each procedure as; general anesthesia (GA), local anesthesia (LA). Results LA was preferred in 245 (80.8%) of 303 patients who underwent TAVI, while GA was preferred in 58 patients (19.1%). Median ages ​​of our patients who received LA and GA were 83 and 84, respectively. The procedure and anesthesia durations of the patients in the GA group were longer than the LA group (p< 0.00001, p< 0.00001, respectively). Demographic and pre-operative clinical data were similar in comparison between two groups (p> 0.05) except for peripheral artery disease. Hypertension was the most common comorbidity in both groups. While the number of inotrope use was significantly higher in patients who received GA (p< 0.00001), no significant differences were found between LA and GA patients in terms of major complications and mortality (p> 0.05). Intensive care and hospital stays were significantly shorter in the LA group (p= 0.001, p= 0.023, respectively). Conclusion The anesthetic technique of TAVI procedure did not have a significant effect on outcomes including; complications, mortality and success of the procedure. LA provides shorter duration of procedure and hospital stay.

Which Inotropic Drug, Dobutamine or Milrinone, Is Clinically More Effective in the Treatment of Postligation Cardiac Syndrome in Preterm Infants?

OBJECTIVE: This study aimed to detect which of the two main medicines suggested in the treatment of postligation cardiac syndrome (PLCS)-dobutamine or mirinone-possesses a more therapeutic effect. While doing this, clinicians are provided with a broader perspective on the treatment and follow-up of cases. The desire was to increase the treatability and monitor ability of the cases in question and hence their survivability. STUDY DESIGN: A retrospective review of a cohort of infants with PLCS was conducted between March 2012 and December 2018. In the treatment of infants with PLCS, dobutamine (dobutamine study group-DSG) or milrinone (milrinone study group-MSG) was used. The respiration, cardiac, echocardiography, and perfusion parameters of the cases were assessed both before and after ligation. Based on the data obtained, both the effects of the medicines on PLCS and the difference between their therapeutic effects were studied. The accuracy of prognostication was assessed with receiver operating characteristic analyses. RESULTS: PLCS was detected in 29 (34.1%) of 85 patent ductus arteriosus ligation cases in total. Of all the PLCS cases, 13 (44.8%) were treated with dobutamine and 16 (55.2%) with milrinone. It was observed that the effects of the medicines on the respiratory system and cardiovascular system manifested in the third and 6th hour, respectively. It was detected that both medicines had more effect on the systolic blood pressure (SBP) (area under the curve [AUC]: 0.997/0.996, p = 0.001/0.002) than on the diastolic blood pressure (AUC: 0.911/0.843, p = 0.032/0.046). CONCLUSION: Dobutamine and milrinone, two primary medicines that can be used in the treatment of cases with PLCS, possess similar therapeutic effects on this pathology. In addition, their postoperative therapeutic effects on the SBP are more in the foreground.

The Relationship Between Plexin C1 Overexpression and Survival in Hepatocellular Carcinoma: a Turkish Oncology Group (TOG) Study.

PURPOSE: Plexin C1 is a transmembrane receptor and plexin C1 overexpression might have role in carcinogenesis. Hepatocellular carcinoma (HCC) has poor prognosis because of its aggressive behavior and limited treatment options, especially in advanced stage. We recently documented that Plexin C1 was overexpressed in HCC. We aimed to evaluate the prognostic significance of Plexin C1 overexpression in HCC in the present study. METHODS: Plexin C1 overexpression was evaluated immunohistochemically on paraffin-embedded blocks of the HCC patients. Plexin C1 immunohistochemical staining was scored. Plexin C1 overexpression staining intensity and prevalence were used for plexin scale staining evaluation and plexin scores were estimated according this staining scale. Plexin C1 score and its association with survival and clinicopathological features was assessed. RESULTS: Sixty-seven HCC patients with adequate tissue for pathological evaluation were included. Median age was 63 years with male predominance (male to female ratio was 4.75 (n 57/12). Well-differentiated HCC (53.7%) patients had higher plexin C1 overexpression (p < 0.05). Median OS was 22.1 months. Patients with lower plexin C1 score (< 12) had shorter OS (17.5 vs 30.1 months, p = 0.036). Neutrophil count, GGT, and PNR (platelet/neutrophil ratio) had prognostic significance (p = 0.047, p = 0.018, and p = 0.045). CONCLUSION: Plexin C1 overexpression is inversely correlated with grade in HCC. The patients with lower rate of Plexin C1 overexpression have worse survival outcome. It might be a prognostic factor in HCC.

The Association Between Cardio-Ankle Vascular Index and Primary Idiopathic Complete Atrioventricular Block in an Elderly Population.

The most common cause of complete atrioventricular block (CAVB) is age-related fibrotic degeneration and is referred to as primary idiopathic complete atrioventricular block (iCAVB). This study aims to investigate the relationship between iCAVB and arterial stiffness using the cardio-ankle vascular index (CAVI).In this study, of 205 CAVB patients, 41 patients with iCAVB implanted with a dual-chamber permanent pacemaker and 40 age- and gender-matched controls were studied. Arterial stiffness was assessed by a VaSera VS-1000 CAVI instrument. The CAVI values of patients with iCAVB were significantly higher compared with the controls (9.63 ± 1.42 vs 8.57 ± 1.12, P < .001). Idiopathic complete atrioventricular block frequency was higher among patients with abnormal CAVI values than those with borderline and normal CAVI (P = .04). In multivariate analysis, only CAVI was an independent predictor of iCAVB after adjusting for other relevant factors (odds ratio, 2.575; 95% CI [1.390-4.770]; P = .003). The present study demonstrated that CAVI, as a marker of arterial stiffness, was increased among elderly patients with iCAVB. Thus, we provide a possible additional mechanism linking easily measured CAVI with iCAVB.

First experiences with a new balloon-expandable Myval transcatheter aortic valve: a preliminary study.

BACKGROUND: In the present article, we present our first experiences with a new type of balloon-expandable Myval valve (Meril Life Sciences, Gujarat, India). MATERIALS AND METHODS: A total of 25 consecutive patients who underwent transcatheter aortic valve implantation (TAVI) from June 2020 to November 2020 were included in the study. RESULTS: The mean age of the study population was 83 (75-87) years; 17 (68%) were female, and 20 (80%) had hypertension. The Society of Thoracic Surgeons (STS) score of the group was 5.4% ± 3.5%. TAVI was performed via the transfemoral route on all patients. In 19 (76%) cases, we started the procedure without predilation. In two (10.5%) cases performed without predilation, the prosthesis did not pass the native valve. We had to implant the valve from the descending aorta in one (4%) patient. We used Prostar XL (Abbott Vascular, Santa Clara, CA, USA) for six (24%) patients and ProGlide (Abbott Vascular) for 19 (76%) patients for vascular closure. Two (8%) in-hospital deaths occurred in our study but there were no deaths in the 30-day and 90-day follow-up. Vascular complications were observed in one (4%) patient. None of the patients in our study had severe paravalvular leak (PVL), while two (8%) patients had moderate PVL. A permanent pacemaker (PPM) was required in two (8%) patients for the indication of complete atrioventricular block. The mean hospital stay for the whole group was 4 (3-7) days. CONCLUSION: Based on our experiences, the new balloon-expandable valve Myval is easy to use, efficient, and has only a few negligible drawbacks such as the need for predilation of the sheath. While shaft flexibility may have advantages in some situations including in very tortuous arteries, it may cause some difficulties in alignment of the valves.

Relation of p - wave dispersion with presystolic a - wave and aortic valve sclerosis in asymptomatic subjects.

BACKGROUND: P-wave duration and P-wave dispersion (PWD) are thought to be the surrogate marker of devoloping atrial fibrillation (AF). The main purpose of present study was to investigate the association between presystolic wave (PSW), aortic valve sclerosis, and PWD. PATIENTS AND METHODS: Patients with sinus rhythm admitted to the cardiology outpatient clinic were consecutively enrolled. Maximum (Pmax) and minimum (Pmin) P-wave duration and PWD were measured. Echocardiography was used to assess the aortic valve morphology and presence of PSW. The patients were divided into two groups according to presence or absence of AVSc and PSW. RESULTS: A total of 100 patients were enrolled consecutively. Patients with both PSW and AVSc had higher PWD values compared with those without PSW (42 ± 15 vs 65 ± 20) and AVSc (52 ± 21 vs 69 ± 19). The patients were categorized on the basis of median PWD values. According to univariate analysis, there was significant association between PWD and presence of PSW (P: .004), presence of AVS (P: .011), hypertension (P: .01) interventricular septal thickness (IVST) (P: .026), and posterior wall thickness (PWT) (P: .022). Multivariate logistic regression analyses demonstrated presence of PSW (95% confidence interval (1.058-6.505, P: .037) as an independent determinant of PWD. CONCLUSION: Assessment of presystolic A-wave on echocardiography examination may provide important information regarding the atrial conduction velocities that is a electrophysiological cause of AF. While there was a significant association between AVSc and PWD in univariate analysis, this significance disappeared in multivariate analysis.

Predictors of time to conversion of new-onset atrial fibrillation to sinus rhythm with amiodarone therapy.

BACKGROUND: New-onset atrial fibrillation (AF) is a frequent cause of presentation to the emergency department (ED). Epicardial fat thickness (EFT) is associated with the presence and recurrence of AF. However, no study has investigated the predictors of the time to conversion of AF to sinus rhythm with amiodarone therapy. The aim of this study was to investigate predictors of time to conversion of AF to sinus rhythm in patients with new-onset AF. METHODS: A total of 122 patients admitted to the ED with symptoms of hemodynamically stable new-onset AF (lasting <48 hours) were registered consecutively. These patients received intravenous amiodarone. EFT was measured using 2D echocardiography in parasternal long-axis views. RESULTS: A significant positive correlation was determined between EFT and conversion time (rho = 0.267, P = .017) in all patients. The median time for conversion from the start of amiodarone infusion was 410 min (150-830 minutes). Based on the median conversion time, patients were classified as early conversion (time < 410 minutes; n = 41) and late conversion (time > 410 minutes; n = 40). Multivariate logistic regression analysis demonstrated that EFT (P = .033, odds ratio [OR]: 1.68, 95% confidence interval [CI]: 1.6-2.7), higher troponin I level > 0.04 (P = .034, OR: 5.3, 95% CI: 1.1-24.8), and lower age (P = .003, OR: 0.8, 95% CI: 0.8-0.9) were significantly associated with longer conversion time. CONCLUSIONS: We determined that EFT and high troponin level affected the time to conversion to sinus rhythm in patients with new-onset AF.

The Prognostic Value of Serum Semaphorin3A and VEGF Levels in Patients with Metastatic Colorectal Cancer.

PURPOSE: Despite new treatment options in metastatic colorectal cancer (mCRC), new prognostic markers are still needed to determine optimal chemoregimen especially for anti-angiogenesis drugs. In this study, we evaluated the serum semaphorin and VEGF-A levels as prognostic factors in patients with mCRC. METHODS: Patients with diagnosed mCRC who were treated with first-line bevacizumab plus chemotherapy were included in the study. Venous blood samples of 37 patients with metastatic colon cancer were taken, and serum semaphorin 3A and VEGF-A levels were studied in pre-treatment and the 1st and third months after the treatment was initiated. RESULTS: Totally, 37 patients were enrolled in the study. The patients' mean age was 62 years. Twenty-eight (49%) of the patients were male, and 19 (51%) were female. Serum semaphorin3A (sema3A) levels of the patients were 5.4 ± 7.4 ng/ml before the treatment, 3.5 ± 3.3 ng/ml at the first month, and 3.5 ± 3.7 ng/ml at the third month. Serum VEGF-A levels were 27.7 ± 32.9 ng/l before the treatment, 23.1 ± 28.1 ng/l at the first month, and 28.9 ± 30.2 ng/l at the third month. There was no significant correlation between the survival and pre-treatment VEGF-A level (p = 0.064). Overall survival (OS) was statistically significantly higher in patients with pre-treatment semaphorin 3A levels below 5.4 ng/ml than higher than 5.4 ng/ml (10.5 months vs 4.5 months, respectively, HR 0.23, 95% CI 19.635-11,391, p = 0.012). CONCLUSION: Pre-treatment semaphorin 3A level can be a prognostic marker for the mCRC patients who were treated with bevacizumab in patients with metastatic colorectal cancer.

¿El licopeno puede eliminar los efectos perjudiciales de la hiperoxia en los cerebros inmaduros? / Can lycopene eliminate the harmful effects of hyperoxia in an immature brain?

Objetivos: Al ser un antioxidante, el licopeno protege a las células contra el daño causado por los radicales libres, fortalece los enlaces intercelulares y mejora el metabolismo celular. Este estudio analiza los efectos del licopeno sobre los trastornos neurodegenerativos por hiperoxia en ratas recién nacidas a término. Métodos: Estas ratas se dividieron en cuatro grupos: grupo 1 de referencia con normoxia, grupo 2 con normoxia + licopeno, grupo 3 de referencia con hiperoxia y grupo 4 con hiperoxia + licopeno. Los grupos 1 y 2 se supervisaron en condiciones de aire ambiental, y los grupos 3 y 4 se supervisaron con un nivel de oxígeno > 85 % O2. Los grupos 2 y 4 recibieron inyecciones intraperitoneales de licopeno de 50 mg/kg/día; los otros grupos recibieron inyecciones intraperitoneales de aceite de maíz con el mismo volumen. Las ratas se sacrificaron en el día 11, después de 10 días con hiperoxia. Se extrajeron los cerebros, y se evaluaron los parámetros del sistema oxidativo. Resultados: Se detectaron lesiones cerebrales por hiperoxia en sustancia blanca, regiones corticales y tálamo. Aumentó la cantidad de células apoptóticas y disminuyó la cantidad de células PCNA positivas en los grupos 3 y 4, comparados con el grupo 1. No se observó una mejora significativa en la cantidad de células apoptóticas y células PCNA positivas en los grupos 3 y 4; además, aumentó la apoptosis. Conclusión: Se halló que el licopeno no mostró efectos terapéuticos para el daño cerebral en ratas recién nacidas. Además, se demostró que el licopeno podría causar efectos tóxicos.

Objectives. In addition to protecting cells against free radical harm thanks to its anti-oxidant nature, lycopene strengthens the bonds among cells and improves cell metabolism. This study focuses on analyzing therapeutic effects of lycopene in hyperoxia-induced neurodegenerative disorders in newborn rats. Methods. Term newborn rats were divided into four groups as the normoxia control group (group-1), normoxia+lycopene group (group-2), hyperoxia control group (group-3) and hyperoxia+lycopene group (group-4). Group-1 and group-2 were monitored in room air while the group-3 and group-4 were monitored at > 85% O2. The group-2 and group-4 were injected with lycopene intrapertioneally (i.p. ) at 50mg/kg/day while the other groups were injected with corn oil i.p. at the same volume. The rats we sacrificed on the 11th day following the 10-day hyperoxia. The brains were removed and oxidant system parameters were assessed. Results. Injury resulting from hyperoxia was detected in the white matter, cortical regions, and thalamus of the brains. It was observed that the number of apoptotic cells increased and the number of proliferating cell nuclear antigen (PCNA) positive cells decreased in the groups-3 and 4 compared to the group-1. No significant improvement in the number of apoptotic cells and PCNA positive cells was observed in the groups-3 and 4, and apoptosis increased as well. Conclusion. This study found that lycopene, did not show any therapeutic effects for brain damage treatment in newborn rats. In addition, this study demonstrated that lycopene might lead to toxic effects.

A case of laryngeal atresia accompanied by persistent pharyngotracheal ductus.

Laryngeal atresia is generally a fatal congenital anomaly with an incidence of 1: 50,000 births. This congenital anomaly is a condition of multifactorial inheritance, in which the fetus has a dilated trachea, enlarged echogenic lungs, an inverted or flattened diaphragm, fetal hydrops, and ascites. Diagnosis is usually made when there is failure to perform endotracheal intubation in a neonate with severe respiratory distress and absence of audible cry. Here, we present a very rare case of a newborn with laryngeal atresia who had respiratory distress and was sustained for the first few minutes of life using partial ventilation via a persistent pharyngotracheal duct. We would like to draw the attention of all physicians to this issue by reporting a rare fatal case of a newborn with a congenital presentation.

Comparison of palonosetron and granisetron in triplet antiemetic therapy in nonmetastatic breast cancer patients receiving high emetogenic chemotherapy: a multicenter, prospective, and observational study.

PURPOSE: We aimed to investigate the efficacy of 0.25 mg dose of palonosetron and granisetron in triplet antiemetic prophylaxis in breast cancer patients receiving HEC. METHODS: Patients with nonmetastatic breast cancer who received HEC [doxorubicin or epirubicin plus cyclophosphamide (AC/EC)] were enrolled in the study. The prophylactic triplet antiemetic regimens were used according to the doctor's preference during the first cycle of HEC as intravenous dexamethasone and palonosetron 0.25 mg or granisetron 3 mg on day 1 as well as oral aprepitant (125 mg on day 1 and 80 mg on days 2 and 3).The primary endpoint was complete response rate (CR) on acute and delayed chemotherapy-induced nausea and vomiting (CINV), separately. RESULTS: A total of 118 female patients were included in the study. Patients received AC (83%), EC (3%), and dose-dense AC (14%) as adjuvant (88%) or neoadjuvant (12%). The majority of patients received palonosetron (59%) containing antiemetic treatment. The CR rate on acute and delayed vomiting was very high and not statistically different in both of the arms (acute 87% vs. 96%, p = 0.089; delayed 90% vs. 92%, p = 0.489), respectively. Nevertheless, the CR rate on either acute or delayed nausea was lower than vomiting (acute 51% vs. 51%; delayed 38% vs. 29%, p = 0.203; respectively). CONCLUSIONS: This is the second study that compared a 0.25 mg dose of palonosetron with first-generation setron in triplet antiemetic prophylaxis in cancer patients receiving HEC. We could not find meaningful statistical differences between two arms, regarding CR rate on acute and delayed CINV.

Association of Aortic Valve Sclerosis and Clinical Factors in Patients With Acute Myocardial Infarction.

BACKGROUND: Since aortic valve sclerosis (AVS) and coronary artery disease (CAD) share similar cardiovascular risk factors, we hypothesized that the clinical profile of patients with acute myocardial infarction (AMI) would be worse in the presence of AVS. The aim of this study was to investigate the association between AVS and clinical factors in patients with AMI. METHODS: Three hundred and fifteen patients with AMI were consecutively enrolled in the study. Echocardiography was used to assess the aortic valve morphology and left ventricular function. The extent and severity of CAD were assessed by Gensini score and the number of obstructed vessels. The patients were divided into 2 groups according to presence or absence of AVS. RESULTS: The overall number of patients with AVS was 132 (41.9%). Patients with AVS were older (69.5 ± 11 vs. 59.5 ± 12 years, P < 0.00001). They also had a higher prevalence of hypertension (61% vs. 45%, P = 0.006), prior CAD (33% vs. 23%, P = 0.041), prior AMI (20% vs. 11%, P = 0.019) and a higher percentage were female (32% vs. 19%, P = 0.007) compared with AMI patients without AVS. There was no significant difference between the 2 groups with respect to the Gensini score (P = 0.372). Prior AMI was associated with AVS on age-adjusted logistic regression analyses. A multivariate analysis showed an independent association between the AVS and prior AMI and age (P < 0.0000001, P = 0.022, respectively). CONCLUSIONS: Our results showed that the presence of AVS is associated with AMI recurrence.

The value of syntax score to predict new-onset atrial fibrillation in patients with acute coronary syndrome.

BACKGROUND AND AIM: New-onset atrial fibrillation (NOAF) has been associated with poor outcome in patients with acute coronary syndromes (ACS). Also, Syntax score (SS) is a scoring system that is derived from angiographic images and is associated with long-term mortality and major adverse cardiac events. In this study, we aimed to assess the relationship between SS and NOAF with known predictors of atrial fibrillation. METHODS: In a prospective, single-center, cross-sectional study, 692 patients who were diagnosed with coronary artery disease for the first time were enrolled consecutively. NOAF was defined as atrial fibrillation, which was documented after hospital admission. SS was calculated by a computer software. Multivariable logistic regression analyzes were used to detect the relationship between variables and NOAF. RESULTS: New-onset atrial fibrillation was detected in 82 patients (11.8%). Patients with NOAF had higher SS (22, interquartile range 18.3-25.1, vs. 12, interquartile range 7-19.5, p < 0.001). According to multivariable logistic regression analysis for NOAF, SS were independently and significantly associated (OR, 1.103; 95% confidence interval, 1.047-1.163; p < 0.001). Other independent predictors of NOAF were TIMI flow <3, C reactive protein, left ventricular ejection fraction, left atrial volume index and E/E' ratio. The optimal cut-off value for SS was 18 for the development of NOAF with 82% sensitivity and 68% specificity (area under the curve: 0.795, 95% confidence interval 0.749-0.841, p < 0.001). CONCLUSION: Syntax score may be helpful to identify for patients who would develop atrial fibrillation in the setting of ACS.

A potential serious complication in infants with congenital obstructive uropathy: Secondary pseudohypoaldosteronism.

Patients who have secondary pseudohypoaldosteronism (PHA) in addition to hyponatraemia, hyperpotassaemia and high serum aldosterone levels for the age were included in this retrospective study.Among eight patients, seven patients were diagnosed with PHA secondary to obstructive uropathy (OUP), whereas one patient had PHA secondary to ileostomy. Six patients with OUP had simultaneous urinary tract infection (UTI) and in all except one patient, secondary PHA recovered with only UTI treatment before applying surgical correction. All the patients were younger than 3 months age. In three patients with PUV diagnosis, salt wasting recurred in an UTI episode under 3 months of age.

The compliance with antiemetic guidelines of Turkish medical oncologists. A survey study of Turkish Oncology Group.

PURPOSE: We aimed to investigate the compliance of Turkish Medical Oncologists to antiemetic guidelines for treatment of acute and delayed chemotherapy-induced nausea and vomiting (CINV) in patients receiving high (HEC), moderate (MEC), and low (LEC) emetogenic chemotherapy. METHOD: A covering electronic mail letter with an online questionnaire link was sent to e-mail and mobile application groups including all 599 members of the Turkish Society of Medical Oncology in January 2018. The online survey has consisted of twelve questions. RESULTS: Questionnaire form was responded by 146 of Turkish Medical Oncologists. The most of the participants were following up more than one antiemetic guideline (53%). While compliance with the antiemetic guidelines was higher in acute CINV prophylaxis for HEC and MEC, it was significantly lower in the delayed CINV treatment of HEC and LEC. The highest and lowest compliance rate was found in the prophylaxis of acute and delayed CINV of HEC (92% and 15%, respectively). The incidence of noncompliance for delayed CINV in HEC was statistically significantly higher in those who worked for ≤ five years in an oncology department, under 39 years of age, and non-academicians (p = 0.004, p = 0.042, p = 0.005, respectively). CONCLUSIONS: Noncompliance with the antiemetic guidelines is continue to be a big problem in Turkish Medical Oncologists. The use of standardized antiemetic protocols in chemotherapy order forms or a computerized decision-support system is now seen as a better tool to enhance compliance with the guidelines.
